Sample Number 298: OXY:Bottle - endpoint at 85% transmissivity, likely overshot. Sample Number 302: OXY:Bottle - titration jumped to plateau portion of curve. Endpoint likely overshot. Analysis methods: ----------------- Salinity samples were collected in 200 ml type ll glass bottles with reusable silicone inserts supplied by Xiamen Cuten Accessories Industry Limited and screw caps supplied by Ocean Scientific International Limited. They were analyzed in a temperature-controlled lab on a Guildline 8400B Salinometer (S/N 68572) standardized with IAPSO standard seawater 23 to 39 days after collection. For details on duplicate analysis see file 2014-018_SAL.pdf. Oxygen samples were analyzed at sea using an automated Winkler titration system (Brinkmann Dosimat model 665 for titrations, Dosimat model 865 for dispensing standards and a PC950 Colorimeter controlled by AutoOxy software V3.4) with modifications based on Carpenter (1965) and adhering to WOCE protocols (Culberson 1991). For details on duplicate analysis see file 2014-018_OXY.pdf. Nutrient samples were collected in plastic tubes. One set of samples was collected and immediately quick frozen in aluminum blocks stored in -20 freezer. Another set of samples from 400 dbar and deeper (to be used for silicate analysis) was collected and stored at 4C in the dark. All samples were returned to IOS for analysis using an Astoria analyzer following methods described in Barwell-Clarke and Whitney (1996). For precision and duplicate analysis see file 2014-018_NUT.pdf. Chlorophyll samples were filtered onto 25mm GF/F filters and stored in glass scintillation vials at -80C prior to analysis. Samples were extracted in 90% acetone at -20C for 24 hours and analyzed on a Turner 10AU fluorometer calibrated with commercially pure chlorophyll a standard (Sigma). Fluorescence readings taken before and after acidification were used to calculate chlorophyll and phaeopigment concentrations (Holm-Hansen et al 1965). Chlorophyll samples were analyzed on board ship during the cruise or at IOS about 6 weeks later. When duplicate samples were collected the average of two samples is reported. Variability is assessed as the CV% (std dev / mean*100). Flags and comments apply to chlorophyll values only. No flags or comments are assigned for Phaeopigment values. For details on duplicates see file 2014-018_CHL.pdf. DMS samples were analyzed at sea. The minimum detectable level for DMS is 0.10 nmol/l, so “0” values should be interpreted as < 0.1 nmol/l. For details on the collection and analysis of the DMS data see file 2014-018_DMS_report.pdf and for duplicates see 2014-018_DMS.pdf. DMSP-D: 20-75 ml of seawater were allowed to flow directly from the Niskin into a magnetic filtration funnel containing a 0.7 µm GF/F filter. The first 3.5 ml were collected in a polypropylene tube containing 50 µl of a 50% sulphuric acid solution. DMPS-T: 3.5 ml of seawater were collected directly from the Niskin into a polypropylene tube containing 50 µl of a 50% sulphuric acid solution. DMSP-D and DMSP-T: Samples were stored in the dark at 4 degrees C for a minimum of 24 hours. They were hydrolized and analyzed later at the Institute of Ocean Sciences. The minimum detectable level is 0.1 nmol/l, so “0” values should be interpreted as < 0.1 nmol/l. For details on analysis see document 2014-018_DMS_report.pdf. HPLC samples were filtered onto 47mm GF/F filters and stored at -80C prior to analysis. Samples were extracted in 95% methanol at -20C for 24 hours and analyzed on a WATERS 2695 HPLC separations system as detailed in Nemcek and Pena, 2014. Analysis was performed ~5 months after collection. The average of two samples is reported. Variability is assessed as the CV% (std dev/mean*100) for duplicate pairs. All pigments below the limit of detection (LOD) are assigned a zero value. TChl-a is the sum of Chl-a, DVchl-a, Chlide-a and Me-chlide. References: 1.

For details on how the transmissivity calibration parameters were calculated see the document Transmissivity_Calculation.pdf. Oxygen:Dissolved:CTD was calibrated using the method described in the Sea-Bird Application Note #64-2 of June 2012 (Sea-Bird_64-2_Jun2012.pdf), except that a small offset in the fit was allowed. For details on the processing see the report: 2014-018-proc.pdf. $REMARKS Quality flags have the following significance: ---------------------------------------------------------------------------------- 0 = Acceptable measurement with no header comment. 1 = Sample for this measurement was collected but not analyzed. Sample lost. 2 = Acceptable measurement with header comment. 3 = Questionable measurement (probably good). 4 = Poor measurement (probably bad). 5 = Measurement not reported (bad). 6 = Mean of replicate measurements. 7 = Manual chromatographic peak measurement. 8 = Irregular digital chromatographic peak integration. 9 = Sample was planned for this measurement from this bottle but was not collected. ----------------------------------------------------------------------------------- $END !-1-- 2- 3- --4--- ---5---- ---6---- ---7---- --8-- --9--- --10- ---11-- ---12--- 13 ---14-- --15- 16 --17- 18 ---19-- 20 --21-- 22 !Samp Bo Bo Pressu Temperat Salinity Sigma-t: Trans Oxygen Oxyge Fluores Salinity Fl Oxygen: Oxyge Fl Nitra Fl Phospha Fl Silica Fl !le_ tt tt re:CTD ure:CTD :CTD CTD missi :Disso n:Dis cence: :Bottle ag Dissolv n:Dis ag te_pl ag te: ag te: ag !Numb ~u ~u vity: lved: solve CTD: ~o ed: ~ed:B ~o ~Nitr ~o Bottle ~o Bottle ~o !er mb en CTD CTD: d:CTD Seapoin tt Bottle: ottle tt ite:B tt tt tt ! er ce Volume :Mass t le Volume :Mass le ottle le le le !---- -- -- ------ -------- -------- -------- ----- ------ ----- ------- -------- -- ------- ----- -- ----- -- ------- -- ------ -- *END OF HEADER 310 23 23 5.2 13.0728 32.2907 24.3067 55.0 6.48 282.3 1.115 32.2785 0 6.475 282.2 0 3.1 0 0.651 0 8.10 0 309 22 22 10.6 12.9390 32.3030 24.3424 54.2 6.51 283.9 1.300 -99.0000 0 6.511 283.8 0 3.1 0 0.653 0 8.24 0 308 21 21 24.9 12.5085 32.2968 24.4207 54.9 6.59 287.4 1.628 -99.0000 0 6.610 288.1 0 3.1 0 0.659 0 8.39 0 307 20 20 50.4 9.2116 32.3688 25.0513 62.4 6.55 285.2 0.611 -99.0000 0 6.550 285.3 6 8.0 0 0.962 0 11.42 0 306 19 19 74.6 7.9080 32.4941 25.3454 65.7 6.29 274.1 0.259 -99.0000 0 6.283 273.6 0 12.7 0 1.193 0 15.37 0 305 18 18 100.1 6.8252 32.8445 25.7702 66.9 5.79 251.8 0.064 -99.0000 0 5.761 250.8 0 19.3 6 1.538 6 23.63 6 304 17 17 125.3 7.1133 33.4088 26.1759 66.7 4.21 183.3 0.049 -99.0000 0 4.203 182.9 0 25.9 0 1.901 0 32.83 0 303 16 16 150.8 7.1705 33.7427 26.4308 66.6 3.37 146.8 0.049 -99.0000 0 3.290 143.1 6 29.8 0 2.100 0 39.08 0 302 15 15 174.9 7.0504 33.8242 26.5115 66.7 3.21 139.8 0.049 -99.0000 0 3.220 140.1 4 30.5 0 2.122 0 41.28 0 301 14 14 199.8 6.7176 33.8748 26.5965 66.7 3.15 136.8 0.048 -99.0000 0 3.150 137.0 0 31.5 0 2.167 0 45.48 0 300 13 13 250.1 6.2948 33.9203 26.6878 67.0 2.42 105.2 0.049 -99.0000 0 2.423 105.4 0 35.5 0 2.428 0 54.19 0 299 12 12 301.0 5.7165 33.9185 26.7590 67.2 2.26 98.4 0.049 -99.0000 0 2.274 98.9 0 37.0 0 2.536 0 61.13 0 298 11 11 400.1 5.3213 34.0041 26.8742 67.3 1.27 55.0 0.049 -99.0000 0 1.308 56.9 4 41.6 0 2.881 0 74.07 0 297 10 10 600.4 4.4693 34.1822 27.1118 67.7 0.39 17.1 0.050 -99.0000 0 0.404 17.6 0 45.6 0 3.208 0 100.56 0 296 9 9 800.1 3.8544 34.3013 27.2710 67.7 0.27 11.7 0.051 -99.0000 0 0.251 10.9 0 46.9 0 3.288 0 120.35 0 295 8 8 1000.9 3.2570 34.3559 27.3729 67.9 0.30 13.2 0.050 34.3570 6 0.271 11.8 6 47.2 0 3.276 0 136.80 0 294 7 7 1250.3 2.9272 34.4529 27.4807 67.8 0.42 18.3 0.049 34.4550 0 0.395 17.2 0 47.2 0 3.266 0 148.37 0 293 6 6 1500.0 2.4948 34.5056 27.5607 67.9 0.68 29.4 0.049 34.5085 0 0.647 28.1 0 46.7 0 3.201 0 160.45 0 292 5 5 2000.4 1.9572 34.5853 27.6685 68.0 1.39 60.2 0.048 34.5859 0 1.353 58.8 0 45.2 0 3.030 0 172.97 0 291 4 4 2500.0 1.7629 34.6245 27.7150 67.9 1.85 80.4 0.043 34.6252 6 1.895 82.3 0 43.6 6 2.922 6 177.07 36 290 3 3 3000.3 1.6574 34.6457 27.7399 67.9 2.20 95.6 0.038 34.6468 0 2.263 98.3 6 42.5 0 2.827 0 176.93 0 289 2 2 3000.2 1.6574 34.6457 27.7399 67.9 2.19 95.0 0.040 34.6476 0 2.272 98.7 0 42.5 0 2.855 0 176.81 0 288 1 1 3274.8 1.6639 34.6486 27.7418 67.6 2.23 97.0 0.038 -99.0000 0 2.370 103.0 0 42.5 0 2.837 0 177.25 0
